A countersink bit is used to?

Explanation:
A countersink bit creates a conical recess so a flat-head screw can sit flush with or below the surface. That recessed seat matches the angle of a flat-head screw head, allowing the screw to sit neatly without protruding. It’s typically used after drilling a pilot hole with a regular bit, to provide the proper seating area for the screw head. It isn’t used to drill a pilot hole by itself, nor to ream or enlarge an existing hole—those tasks have different tools and purposes.
